It is well-known that the inner of AC adapter is a switch power supply working under high voltage, huge current and heavy load. On the other hand, it is closed cycle with no hand holes in the cover or fan inside to help radiate the heat. As a result, the AC adapter is usually in high temperature while working. Especially in summer, even touch the surface of the adapter you can feel the high temperature, not to mention the inside. As a result, you should maintain and protect your AC adapter in daily work and entertainment.

1. Creating fine heat radiating environment

In high temperature, when you use a laptop, make sure that it is placed in ventilating environment and no straightaway sunlight, otherwise the AC adapter absorb heat instead of radiating. In hot summer, we can place the AC adapter on one side to increase the interface area between the AC adapter and the air, thus, the heat could be radiated more quickly.
Furthermore, we can put a narrow plastic or metal to increase air convection and prompt the heat radiation.

2. Any abnormity requires instant discontinue. When the AC adapter gives out noises even smoke, you are suggested to stop using it and cannot reuse unless professional engineer checks it out because in that case something must be wrong in the machine.

3. Charge appropriately. You had better not operate 3D games or other processor burden the whole machine in case that the output power is not adequate enough that the charging rate slows down or over-burdened or cannot be fully charged.

4. Different-type adapters are not suggested to use alternately.

Differentiation exist in output connector, voltage and current among different laptop adapters, as a result, they are not suggested to use by turns. Even of the same brand, laptops of different model numbers are not suggest to use alternately until testified by professional engineer.
Laptop heating in summer is inevitable so that we should pay more attention to the surrounding environment.
